COUPLING FOR BRAKE-RODS.

SPECIFICATION formingpart of Letters Patent No. 276,370, dated April 24, 1883 Application filed March 9, 1883. 7 (Model) To all whom it may concern Be it known that I, EDWARD EBI, of Cedar Rapids, Linn county, lowa, have-invented a new and Improved Coupling for Brake-Bods, of which the following is a full, clear, and exact description.

This invention relates to the brake-rods extending the length of the train for operating all the brakes simultaneously, and has for its object to facilitate the coupling of the brakerods of the several cars of a' train.

The invention is an improvement of the brake-rod for which United States Letters Patent No. 265,773 were issued to me on the 10th day of October, 1882; and itconsists of guideblocks loosely mounted on the brake-rods, and

provided at the outer ends with beveled pron gs,

which guide-blocks guide the clutch-disks at the ends of the brake-rods together, so that theycan engage. The blocks are provided with devices for locking them together.

The invention also consists in certain parts and details and combinations of the same, as will be fully set forth and described hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal elevation of my improved coupling for brake-rods, showing the manner in which it is applied. Fig. 2 is an end elevation of the same, showing thelatches K in difl'erent positions; and Fig. 3is a perspective of one of the coupling-blocks, showing the latch removed.

The ends of the brakerods A, held longitudinallyunder thecars, are journaled in downward projections A on the ends of the car, and to theendsof therodsArodsBarehinged, which terminate in clutch disks 0, having teeth on the end circular surfaces.

On the rods B guide-blocks D are loosely mounted to turn in such a manner that the clutch-disksG will be containedwitnin recesses on the said blocks. The blocks D are provided in the free ends with recesses formingtwo diagonally-opposite beveled tapered prongs, D, on the outer end of each block. The edges of each prong are formed by two diagonal lines extending from two diagonally-opposite corners at the inner end of the block to a point at the outer end of that edge which is between the two diagonally-opposite edges at which the lines start at the inner end of the .block. Both prongs D are made'in the same manner. A collar or flat ring, E, is loosely mounted on each rod B between the inner end of a block, D, and a fixed collar, F, mounted on the rod B. A spiral buffer-spring, G, surrounds each rod 13 between the collarF and the projection A. The ring or collar E is provided at diametrically-opposite points with a pair otjaws, H, between one pairof which alocking-bar, J, is pivoted. One of thejaws ot' the other pair is provided with a pivoted spring hook latch, K, adaptedto swing in the plane of the collar. The end of the prong of the hook is beveled.

Each block is provided at the inner end of one surface with an eye or ring, L, through jeets from the projection A. The mi N is also suspended by means of a chain, N, from the draw-head 0. At its free end each locking-bar is provided with a beveled notch, I.

The operation is as follows: When the cars come together, the beveled sides of the projections D of the blocks D strike against each other until they fit snugly, and thereby guide the clutch-disks 0 against each other, so that they can engage. The coupling-blocks D are then looked together by swinging the free ends of the locking-bars J in between the corresponding jaws, H, provided with the latches By pressing the bars J between thejaws H the latches K will be pressed outward. and will then snap back under the action of the springs, and thus lock the bars Jin place. The blocks D thus serve as guides, and greatly facilitate bringing the clutch-disks (I together, so that they can engage.

Having thus described my invention, Iclaiin as new and desire to secure by Letters Patent-- 1. The combination, with brake rods, of clutch-disks on the ends of the same, and of guide-blocks provided on the outer ends with beveled pron gs,which blocks are loosely mounted on the ends of the said rods, substantially .as herein shown and described, and for the.

purposes set forth.

2. The combination, with brake rods, of clutch-disks on the ends of the same, guidehlocks loosely mounted on'the said rods and provided at the outer ends with beveled pron gs,

which a horizontal rod, M, passes, which proand of rods for locking the blocks together,

substantially as herein shown and described,

and for the purpose set forth.

3. The combination, with the brake-rods A, of the rods B, hinged thereto, the clutch-disks C'on the ends of the rods B, the spindle-blocks.

prongs D, the eyes or rings L, and the'rods M, passing through the said rings or eyes, substantially as herein shown and described, and for the purpose set forth.

6. The combination, with brake-rods, of the clutch-disks O, the blocks D, having beveled prongs D,th'e eyes or rings L,the rods M, and the chains N, substantially as herein shown and described, and for the purpose set forth.

7. The combination, with brake-rods, of the clutch-disks C, the blocks D, having beveled prongs D, the loose collars E, havingjaws'H, the locking-bars J, the latches K, and the fixed collars F, substantially as herein shown and described, and for the purpose set forth.

EDWARD EBI."
